Easy question - How can I save this variable within the for loop?

Hi!

I have one easy question, but weridly I am not being to solve the problem. Say I have this very simple code -

for n = 1:10
    A = [1 n 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16];
    B{n} = A(1,2)*10;
end

How can I save all ten As in a cell/structure? (Just like the code save every updated B)

Thank you!!

hello

If I understand correctly , n must be multiple of 10 and that's the only values of interest for A and B, no need to perform other n values computations that are not multiple of 10

you can simply do that

for k = 1:10
    n = k*10;
    A = [1 n 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16];
    B{k} = A(1,2)*10;
end

B

B = 1×10 cell array
    {[100]}    {[200]}    {[300]}    {[400]}    {[500]}    {[600]}    {[700]}    {[800]}    {[900]}    {[1000]}

Hi! Yes, you got the point right. But the code is not saving the updated matrix A everytime. I want all 10 A's to be saved!

Just like all the B's are saved in a cell array.

hello again

so you want this ?

for k = 1:10
    n = k*10;
    A = [1 n 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16];
    B{k} = A;
end

B{1}

ans = 4×4

1 10 3 4 5 6 7 8 9 10 11 12 13 14 15 16
